Product Overview:
HEM750 Fracturing Truck Controller is used for single fracturing truck control, which can realize functions of manual start and stop, throttle control, gear position control, data measurement, alarm protection and “four remotes” (remote control, remote measuring, remote communication and remote adjusting). It applies split mode of “Master Control + Display” and transmits data through RS485.
The display module of the controller applies 8-inch 800*600 resolution capacitive touch screen with Chinese and English display, which can realize the control, data monitoring and parameter adjustment of the master control module with simple operation and high reliability.
The master control module of the controller accurately monitors various working status of engine, gearbox and plunger pump, making it possible to realize the precise control and alarm protection for the plunger pump. It has SAE J1939 interface and can communicate with a variety of ECU (ENGINE CONTROL UNIT) who has J1939 interface. Compared with PLC controlled fracturing truck system, it has compact structure, simple connection and higher reliability.
PERFORMANCE AND CHARACTERISTICS
HEM750 controller is used for the data monitoring and control of a single fracturing truck. It consists of two modules: HMU8-750 (Display Module) and HEM750 (Master Control Module), and the two modules are connected through RS485 communication.
The display module adopts an 8-inch LCD with 800*600 resolution, HMI display and capacitive touch screen operation. Chinese and English operations are optional for on-site selection and convenient for commissioning staff;
The display module can record and display the last 2000 outlet pressure and flow data points after the plunger pump’s work, and the recording interval is 5 seconds;
The speed of homepage interface of the display module, sensor head and bar chart could display the alarm set value and maximum range of the master control module;
With the control functions of engine emergency stop, startup, shutdown, throttle increase/decrease and slight increase/decrease;
With the control functions of upshift/downshift of gearbox, one-key idle and brake.

A variety of temperature, pressure, level sensor curves can be directly used, and the sensor curve could be customized;
Crank disconnect conditions (speed and oil pressure) can be selected;
With perfect fault protection function and can display fault details;
RTC display and even log function, which can circularly record 200 data;
With the customized description display function, it can display the customized description character string set by the master control module;
Allow users to change and set the parameters of the display module, which will not be lost in case of power failure. All parameters are changed through the touch screen;
Allow users to change and set the parameters of the master control module, which will not be lost in case of power failure. Most parameters of the master control module can be changed through the display module, all parameters of the master control module can be adjusted through PC software;
All parameters are applied digital adjustment, which eliminates the simulation adjustment method of conventional potentiometer, and improves the reliability and stability of the whole unit;
Adapt to environment of the starting battery voltage 12/24VDC;
With maintenance function, and the maintenance type can be selected as date, running time or date + running time, and maintenance time due action can be set (indication, warning, fault idle, cooling shutdown and alarm shutdown);
With the speed regulation functions of CAN, GOV and relay.
HMU8-750 DISPLAY MODULE
It is used for parameters displaying collected by the master control module, the control of the main control module and parameter adjustment can be realized through the touch screen.
With power indicator, communication indicator and alarm indicator;
The module has 10 levels of dimming, which can adjust the brightness according to different environments;
With 4 RS485 interfaces, 1 CANBUS interface, 1 ETHERNET interface, among which the RS485-1 communicates with the master control module, and the others are reserved interfaces;
With USB device interface, used to upgrade the firmware of the display module;
With USB host interface, used to upgrade the interface picture and font library of the display module;
A rubber sealing ring is designed between the enclosure and the control panel. The waterproof property of the front panel can reach IP65;
The controller is fixed with metal clips;
Modular structure design, pluggable wiring terminal, embedded installation mode, compact structure and easy installation.
HEM750 MASTER CONTROL MODULE
It is used for the data acquisition, monitoring and protection of engine, gearbox and plunger pump to realize the control of engine start and stop, throttle and gear position.
